Sorry for being so harsh—I didn’t mean to be rude. I understand that people have different needs, but sometimes we just need to move on and adapt; that was my whole point. There’s a USB-C to 3.5mm Apple dongle—I used it with my iPad Pro, and it’s even better than the Lightning version. Hope it works for you.
Sorry again—old habits from the army die hard. I just wanted to say that I was the same, but eventually, I gave up. I was an audiophile back then, too.
Fairphone should not have copied Apple and Google’s BT in-ears with batteries. It’s e-waste indeed. I have two brands of wired in-ears; Shure and Sennheiser. The first is quite old but still fine. It’s true that generally the sound quality of wireless BT is not as good as wired . I really hope an adapter will work with Jolla2. Husband uses an adapter with Pixel 5 and e/OS. That does the job.
Have you used it with a SF phone successfully, and then reliably on an ongoing basis?
If not, then an experience that an Apple accessory works well with a matching Apple product offers pretty close to zero information about it working on a non-Apple, non-Android niche OS.
Perhaps it will, perhaps it won’t. Unless it is something you have tried, you are making an uninformed comment, that tries to discourage a “sure to work” option for an “I can imagine how well it would work in my head” option.
Sadly this summarises a large part of tech development, and is a major contributor to enshitification.
@Mister_Magister even soldered one on his computer if I remember correctly. Never heard anyone having issues with their dongle on any device.
Apparently you haven’t read this thread, so I shall repeat myself.
I bought a USB-C headphone adaptor. I plugged it into my Xperia 10III. It did not work.
Now you have heard it, and now you know that it did not work for at least one person.
So you can move right along to pointing out why this was a special case, and actually it does work, and I can’t actually tell when it doesn’t work, because you have not actually tried it yourself on a SF phone, and so you know it works.
(I’m starting to channel my inner @Mister_Magister …)
Slow down you said “I bought a USB-C headphone adaptor.” not “I’ve bought apple’s 3.5mm usb-c dongle”
These are not the same things. For example adapter that comes with android phones like asus or oneplus, are not, in fact, DAC+AMP, but they somehow wire into onboard DAC+AMP. apple’s dong is full amp+dac, not just physical adapter. if you plugged it in, and you have usb OTG working, then doing lsusb should result in the adapter being listed in there, same as aplay -L
Same here, you did not say it was apple’s dong
(i was mentioned so I was summoned)
It’s good that we have one person as a reference at least.
Did you verify that is sfos specific or device specific if you have more devices?
Other than that, if it makes you feel any better you might use it on something else in the future. It’s a 9.99 type c dongle, worth the gamble and to have one in your bag 
I personally am a big fan of the 3.5mm jack. Seriously. But I kept my mouth shut. This legacy technology will not be part of new phones of most makes. It will not be a feature of the J2.
Get used to it an stop whining like 4 year olds.
And: No. No 3.5” screen either.
Get used to it. Or get some nice refurbished N900.
but they somehow wire into onboard DAC
btw the somehow is probably USB-C Audio Adapter Accessory Mode - deprecated in 2024.
just for prosterity, i love a 3.5mm output. i use many phones, and when they have no 3.5 it’s ok, I’ve got lovely Sennheiser hd 250 bts that are fantasic.
but i notice when i have my 8110 or 10iii I’m much happier, i can use the 250’s OR my Amperiors/px 200s/ portapros etc. it’s just better.
so def. will be on the waiting list for the first TOH with 3.5.
3.5mm is far from being legacy, it’s not even close to being legacy
If jolla phone 2 and toh2 won’t be a vapourware, I’ve already talked with my audio buddies and we have idea of how to put quite good dac+amp on there 
Audiojack seems better because of the audio compression codecs used in the Bluetooth protocol.
I pretty sure it’d been mentioned before, but with Jolla not including an audio jack they’ve effectively obligated themselves to implementing a more recent/better Bluetooth audio profile in the version of SFOS to ship with the J2.
that’s a bucketload of wishful thinking
Also, why would one consider Bluetooth the only alternative to 3.5mm Jack? There are numerous native USB-C devices.
There are multiple reports that USB-C adapters do not currently work well. From this thread:
See also this bug report: Xperia 10 III can't use Type-C headphones
I’m hopeful that routing audio and microphone through a USB-C adapter is a solvable problem and the Jolla Phone will come with support, but I would love to have confirmation from Jolla.
That ties in to the “Apple Dongle vs Asus/Oneplus adapter” comment by Mister_Magister above I assume. I am talking about purely digital headsets/earphones.
Either way. If you don’t offer a jack, supporting USB-C native earphones should be something to be secured, especially on own hardware.
I have switched to Fairbuds (battery exchangeable, so not instant electronic waste), but I do understand those wanting a headphone jack, but for mechanical reasons: a USB C plug is much longer than an angled headphone plug. So the momentum it transfers to the jack is much higher and the likelihood of a mechanical damage of the phone is much higher with the usb c plug.
